TESTS ON COLLECTORS TO REMOVE IODINE FROM VENTILATION AIR
Technical Report
·
OSTI ID:4137562
Laboratory tests to evaluate the use of a number of materials for removing iodine from air streams indicated that charcoal was very effective (99.9%). Wire-mesh collectors offered the advantage of a much lower resistance to air flow as compared with charcoal, but the iodinecollecting efficiency for the two metals tested was lower than for charcoal. Silvered copper mesh indicated efficiencies generally higher than 98% for room-temperature air flowing at velocities as high as 5 ft/sec through 4- or 5-in.-deep beds of density l8 to 60 lb/ft/sup 3/. Copper mesh performed erratically, showing efficiencies from 99.8 to 15% and averaging 50% for 34 6-hr tests. Iodine concentrations from 10/ sup -7/ to 134 mg 1/sub 2//m/sup 3/ air were tested.
